B: Short Order
Tap the B button to make burger buns, beef patties, tomatoes, lettuce, and cheese fall from the sky. This can be used as anti-air projectile.
Side+B: Hurdle Jump
Input Side+B to summon a hurdle that Track Meet leaps over. The hurdle blocks projectiles and prevents characters from walking past it (they must jump over it or go under it).
Up+B: Power Pad Lift
The NES Power Pad peripheral appears underneath Track Meet's feet. Track Meet runs in place as the Power Pad acts like a flying carpet.
Down+B: Eggsplode
Input Down+B to summon a chicken. Input Down+B again to summon a fox. The fox runs to the chicken and places a bomb under the chicken. Input Down+B again to make the bomb explode.
Final Smash: World Class Track Meet
I was thinking Track Meet and a bunch of athletes could run in high speed and trample on his enemies... kinda like Breakneck Blitz from Pokémon.
